Ok so I've been upgrading my hay equipment and I need a few more ponies under the hood of my tractor. I'm cutting with a krone disc nine with rollers and a br740 bailer. I'll also be tugging a fertilizer spreader and 16 ft grain drill. I'm not looking to buy a brand new one and I will not consider a Kubota I have one already and I hate it. I really like the 6000 series jd's but I'm not sure what size is best. It has to be 4wd and i will need a loader on it. What are you guys using?
